This should work.  I struggled a bit myself before realizing that the
documentation says an export should always *precede* its definition.
Maybe you missed that too.

For instance, this works:

  (module foo ()
    (import scheme (chicken module))
  
    (define-syntax define&export
      (syntax-rules ()
        ((_ ?name ?value)
         (begin (export ?name)
                (define ?name ?value)))))
  
    (define&export x 1))

  (import foo)
  (print x)

Hope this helps!
